Santa Fe - Former England skipper Chris Robshaw returns to the England team after recovering from injuries for the series-deciding second Test against Argentina in Santa Fe Saturday.
His inclusion is one of three changes from the side that started in a thrilling last-gasp 38-34 first Test triumph in San Juan last weekend.
Uncapped fellow flanker Sam Underhill is also called up by Australia-born coach Eddie Jones for the match at Estadio Brigadier Estanislao Lopez in northeastern city Santa Fe.
They take over from teenager Tom Curry, one of the stars of the first Test, and equally impressive Mark Wilson, who is among the eight replacements.
The third change is at inside centre with Piers Francis, who played Super Rugby this year for the Auckland Blues, replacing Alex Lozowksi, another substitute this Saturday.
Robshaw, captain of hosts England when they were eliminated after the first round of the 2015 World Cup, has been hampered by shoulder and ankle injuries.
He missed the Six Nations Championship campaign this year and was ruled unfit for the first Test against the Pumas last weekend.
"It is great to welcome back Chris Robshaw into the squad. He would have been disappointed to miss the first Test, but has worked hard to be ready for this weekend," said Jones.
"'Robbo' has been one of the best England players over the last two years and he will add a lot of experience and work rate into our back row.
"It will also be exciting to see Sam Underhill make his debut,having been unfortunate not to play last weekend because of injury.
"We will need to improve our performance from last weekend if we are going to win on Saturday, but we have prepared in detail and intensely this week.
"Argentina will be a much better and stronger side than last weekend so the message to the guys all week has been that it is up to us to raise our levels.
"Despite missing 30 players on this tour, we set out to win the series 2-0. It would be a fantastic achievement for this young and talented squad to do that.
"On Saturday we want to finish the season and the halfway point of a four-year World Cup programme on a real high."
England are chasing an eighth consecutive victory over the South Americans.
